CC2540 bluetooth Power class 1?

Hi Hec,

Thanks for your good guide..

according to your below mentioned that means possible to +10 dBm?

So Is it possible to design with 10dBm?

And also Do you have the reference design(schematic) to provide?

Thanks,

Eric.

I think what you are after is:

This document " shows the proper way to supply the CC2540 with the TPS62730 DC/DC converter for current savings of up to 30% in active mode. The TPS62730 converter is controlled by the CC2540. "

Good luck!

You could add a TI CC2590 2.4GHz RF Front End device.

In this scenario would we control the TX PA and RX preamp EN lines (i.e. the T/R switch) with GPIO on the processor running the stack (i.e. the 8051 inside the CC2540)? 

How much link budget improvement do we get on the receive side from the RX preamp?  To get RX link budget improvement do we need a filter between the preamp and the receiver? 

Thanks!!

That is correct. The 8051 will control the CC2590 via the GPIO on the CC2540.

This function will become a part of the stack.

You can expect an improvement of 8-10dB of link budget improvement.

Sorry I misread your question :)
